You can put this solution on YOUR website!
To solve this you use the FOIL method;
F=first
O=outside
I=inside
L=last
(x-9)(x-11)
Multiply first terms in each set of parethesis;
x(x)=x%5E2
Multiply outside;
x(11)=11x
multiply inside;
9(x)=9x
multiply last;
9(11)=99
So you have;
x%5E2-11x-9x+99
Add like terms;
x%5E2-20x+99
Hope you understand;
=)
